1. EXPOSED PAD. THE EXPOSED PAD ENHANCES THERMAL PERFORMANCE
AND IS ELECTRICALLY CONNECTED TO GND INSIDE THE PACKAGE. IT IS
RECOMMENDED TO CONNECT THE EXPOSED PAD TO THE GROUND PLANE
ON THE BOARD.

Enable Input. Drive EN high to turn on the regulator; drive it low to turn off the regulator. For automatic
startup, connect EN to IN.

SENSE
Sense. Measures the actual output voltage at the load and feeds it to the error amplifier. Connect SENSE as
close as possible to the load to minimize the effect of IR drop between the regulator output and the load.

ADJ
Adjust. A resistor divider from OUT to ADJ sets the output voltage.

EP
Exposed Pad. The exposed pad enhances thermal performance and is electrically connected to GND inside
the package. It is recommended to connect the exposed pad to the ground plane on the board.
